Electro Hardware MS1009M07F16D Round Board Spacer M3

Product Description

The ELECTRO HARDWARE MS1009M07F16D is a round, female unthreaded circuit board spacer designed to maintain precise standoff distance between a PCB and a mounting surface or between stacked boards. Machined from Grade 303 stainless steel to the QQ-S-763 fastener standard, it delivers corrosion resistance and dimensional stability in demanding environments. The spacer measures 5 mm overall length with a 6 mm outside diameter and accepts an M3 screw through a 3.2 to 3.6 mm inside diameter bore. The bright, uncoated finish leaves the stainless surface exposed for direct inspection of material integrity. Electronics assembly technicians and panel builders install this spacer during PCB mounting operations where consistent board height and reliable hardware are required.

This spacer suits M3 metric fastener applications in electronics manufacturing, control panel assembly, and circuit board mounting within HVAC control boards, electrical enclosures, and similar equipment. Its compact 6 mm OD profile fits standard PCB mounting hole patterns without crowding adjacent components. The unthreaded female body style is used where a bolt or screw passes through from the opposite side, making it appropriate for through-bolt standoff configurations. Minimum order quantity is 10 units and package quantity is 1 per package.

Key Features

• Grade 303 stainless steel construction meets QQ-S-763 fastener standard for consistent material quality
• 5 mm overall length with tight length tolerance of -0.130 to 0.130 mm for precise board standoff height
• 6 mm outside diameter fits standard PCB mounting footprints without component interference
• 3.2 to 3.6 mm inside diameter accommodates M3 screws with an inside diameter tolerance of 0.000 to 0.270 mm
• Bright uncoated finish — no coating buildup that could affect dimensional fit in tight assemblies
• Female unthreaded body style supports through-bolt standoff configurations

Compatibility

Designed for use with M3 metric screws in round-body female unthreaded standoff applications on circuit boards and electronic assemblies.

Installation Notes

Installation is performed by electronics assembly technicians or electricians during PCB mounting or control panel build. Always de-energize the assembly and follow applicable lockout/tagout procedures before working on any circuit board or enclosure. Use a properly sized M3 fastener to avoid cross-threading or deforming the spacer bore. Do not over-torque the mating screw, as the unthreaded bore does not provide thread engagement and relies on the mating hardware for clamping force.
